Seafaring is a risky occupation when compared to land-based industries as incidence rates of mortality and morbidity are higher. Seafarers face very specific job-related cardiac risk factors, such as time pressure, high stress factors onboard, or long working hours. In the 1980s and 1990s, deaths due to cardiovascular disease accounted for 55% to 70% of all natural causes of death among seafarers on British and Danish merchant ships. The coronary heart disease（CHD﹚risk is influenced by independent coronary risk factors, namely age, LDL cholesterol, smoking, HDL cholesterol, systolic blood pressure, family history of a premature myocardial infarction, diabetes, and triglycerides, as well as dependent risk factors, i.e. overweight, lack of exercise, high-fat diet, alcohol and stress. However, research which has empirically documented the link between Taiwan seafarers’ exercise behavior and coronary risk is scant. In this study, the association among exercise behavior, handgrip strength, insulin resistance, lipid profiles, job-relative factors（rank, workplace﹚were assessed.
Methods:
The study employed a cross-sectional design on the health characteristics of seafarers. Data collection from Jan. 2016 to Oct. 2016. In total 142 male seafarers aged 30-60 years were recruited from a health evaluation center at the Zuoying branch of Kaohsiung Armed Forces General Hospital. Their exercise behavior were assessed using the International Physical Activity Questionnaire (IPAQ) short form and Behavioral Regulation in Exercise Questionnaire-2(BREQ-2). In addition, insulin resistance(HOMA-IR), handgrip strength, lipid profiles were also measured. We investigated the influence of exercise behavior on coronary risk factors.
Results:
The study participants were, on average, 43.70±9.45 years old and had a median body mass index (BMI) of 26.5[24.1 to 28.9] kg/m2. At sea, non-officers were more likely to be physical active than officers (p<0.01). IPAQ-reported sitting time and body mass index were observed about their positive relationships (p<0.05). The findings show that IPAQ-reported sitting time at sea was significantly correlated with triglyceride (p<0.0001). IPAQ-reported sitting time on land and exercise frequency on land were associated with relative autonomy index (RAI) (p<0.05). MET minutes of activity on land and exercise frequency on land were associated with HOMA-IR in men aged 50 to 60(p<0.05). In the motivation profile, identified regulation and intrinsic regulation appeared to be important determinants of exercise behavior on land (p<0.05). To provide fitness equipment onboard is positively correlated with MET minutes of activity at sea (p<0.05).
Conclusion:
Recommended the seafarers engaging in various physical activity, increasing physical activity levels, and decreasing sedentary behavior time in order to achieve the purpose of cardiovascular disease prevention. In health promotion programs, BREQ-2 could be used as a clinical tool for seafarers’ participatory motives evaluation.
